This is the real issue, but there has probably been alot of debate about this already? What made you take your current stance?
I went though the body scanner this Monday in Cincinnati, well aware of the fact that they can see your penis etc (and it was cold that day...). It didn't bother me that much, but it was much more time consuming than going through the old metal detectors, and I don't like the fact that this could be harmful (but I haven't researched how credible this is).
